IMPROVEMENT IN RAILWAY-CAR COUPLINGS.

Specification forming part of Letters Patent No. 119,416, dated September 26, 1871.

To all 'whom it may concern:

, Beit known that I, GEORGE C. SHERMAN, of Chicago, in the county of Cook. and State of Illinois, have invented-a new and valuable Improvement in Car-Couplings; and I do herebydeclare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this specification, and to the letters and iigures of reference marked thereon.

Figure l is a partial vertical longitudinal section of my invention. Fig. 2 is a top view of the same.

rIhis invention relates to car-couplings; and it consists in a novel arrangement' of devices for removing and replacing the coupling-pin, the object being to providea simple and effectual means of nncoupling and coupling cars that necessitates no exposure to danger in conducting the operation. l

A represents the part or head of the coupling connected to the car, and it is constructed in J[he general form shown, having a beveled opening, B, to receive the link b, and upward projections c and c to support the crank-shaft d. The shaft d has a laterally-projecting arm, e, to which is attached a rope, e', that passes up through an opening, f, to a conyenientplace for the hand of the operator; a downward-proj ecting link, g, that connects with a vertical projection, g', on the head of the couplingpin d', is formed on the central portion of the shaft d. The coupling-pin d is enlarged at h to give weight, and to afford it a support on the sides of the slot 7L in the upper portion of the head A. The-pin may also be enlarged and shaped as at hf, so that when its lower portion is struck by the link in coupling this projection will tend to carry the pin upward on the projection h between the inner end of the projections c and c', and thus lessen the backward swing of the point of the pin. The lower portion c of the head A also has a slot, h, through which the pin d passes. The slots h and h permit the proper vertical and lateral motion of the pin as it is drawn up and dropped down in connecting and disconnecting with the link b by means of the rope c', arm e, shaft d. and link g, and inv its'upward motion by the additional aid of the projection hm and the blow from the link. A second pin may be used back of the pin d to take up more of the link and draw the cars closer together.

I claim as my invention- The draw-head herein described, provided with the angular projection hf in rear of the pin and with the rock-shaft d, having loop g and operating-arm e, in combination with the pin having a globular expansion h at its upper portion, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

' GEORGE C. SHERMAN.
